IFU EN 2019 NCoV 19 Saliva Ag EASY Test
If you don’t like the idea of nasal or throat swabs tests, our new highly accurate Saliva tests could be the answer.
These lateral flow tests are accurate, fast, and comfortable to use, and more importantly, it eliminates the close contact with the examiners, reducing the risk of viral exposure.”
Our New COVID-19 Antigen test from dispenses with the unpleasant and sometimes painful nasopharyngeal swabs and can provide evidence of a possible COVID-19 outbreak within the office comfortably within 10minutes with only a little saliva with a gold standard specificity of 100% and a remarkable sensitivity of 94%.
Each Coronavirus Ag Colloidal Gold Saliva Lateral Flow Test includes all necessary reagents and requires no additional specialist equipment to conduct a successful COVID-19 test in only 10 minutes, this makes the test ideally suited for workplace testing schemes.
ADVANTAGES OF SALIVA ANTIGEN TEST KIT
1. Convenient and effective for collecting SARS-CoV-2 samples.
2. Painless (no patient discomfort and anxiety for sampling).

*Any saliva specimen is appropriate for testing but the saliva specimen collected in the morning, before mouth rinsed, eating or drinking, is recommended
INTERPRETATION OF TEST RESULTS
This product can only perform qualitative analysis on the detection object.
If both C and T lines are visible within 10 minutes, the test result is positive and valid.
If test area (T line) has no color and the control area displays a colored line, the result is negative and valid
The test result is invalid if a colored line does not form in the control region. The sample must be re-tested, using a new test.
The test contains a built-in internal control in the test card. A color band appearing in the control region (C) is designed as an internal control. The appearance of the control line confirms that sufficient flow has occurred, and that the test card is working normally. If the control line does not appear within 10 minutes, it is considered an error in the test result and it is recommended to test again with the same sample and a new device.
- The result of the test should not be taken as a confirmed diagnosis, for clinical reference only. Judgement should be made along with RT-PCR results, clinical symptoms, epidemiological information, and further clinical data.
- The Test performance depends on the amount of virus (antigen) in the sample and may or may not correlate with viral culture results performed on the same sample.
- The test must be equilibrated to room temperature (18℃~26℃) before used, otherwise the results may be incorrect
- A negative test result may occur if the level of antigen in a sample is below the detection limit of the test.
- Failure to follow the Test Procedure may adversely affect test performance and/or invalidate the test result.
- React less than 10 minutes may lead a false negative result; React more than 10 minutes may lead a false positive result.
- Positive test results do not rule out co-infections with other pathogens.
- Negative test results are not intended to rule in other viral or bacterial infections.
- Negative results should be treated as presumptive and confirmed with a molecular assay.
- Clinical performance was evaluated with fresh samples.
- Users should test specimens as quickly as possible after specimen collection.
1. Clinical Verification
The performance of Test was established with 232 sample collected from symptomatic patients, who with symptoms onset within 7 days.

2. Limit of Detection
The experimental results show that for the virus culture concentration above 100 TCID50/mL, the positive rate of detection is greater than or equal to 95%. For the virus culture concentration of 50 TCID50/mL and below, the positive rate of detection is lower than 95%. So, the limit of detection of the Test Card is 100 TCID50/mL.
